Multi-threaded decoding can be more memory-consuming than single-threaded decoding, FFmpeg developers do not agree whether this is unavoidable or a disadvantage of our implementation. > (so that more threads used, more memory required?) > > I tried to decode an H.264 encoded 4K video using command: > ffmpeg.exe -v error -i a.mp4 -threads 0 -f null - 2>error.log How did you encode the H.264 input file?
